Blockchain

KSI is a blockchain technology designed in Estonia (developed by Guardtime) and used globally to make sure networks, systems and data are free of compromise, all while retaining 100% data privacy.

With KSI Blockchain deployed in Estonian government networks, history cannot be rewritten by anybody and the authenticity of the electronic data can be mathematically proven. It means that no-one – not hackers, not system administrators, and not even government itself – can manipulate the data and get away with that.

Guardtime established its company in 2007 with the goal of creating a formally verifiable security system for the Estonian Government.
